Abnormal cerebral hemodynamics and blood-brain barrier permeability detected with perfusion MRI in systemic lupus erythematosus patients. Neuroimage Clin 2023; 38:103390. [PMID: 37003131 PMCID: PMC10102558 DOI: 10.1016/j.nicl.2023.103390] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 03/24/2023] [Accepted: 03/25/2023] [Indexed: 03/30/2023]
Abstract
OBJECTIVE Dynamic susceptibility contrast (DSC) magnetic resonance imaging (MRI) has previously shown alterations in cerebral perfusion in patients with systemic lupus erythematosus (SLE). However, the results have been inconsistent, in particular regarding neuropsychiatric (NP) SLE. Thus, we investigated perfusion-based measures in different brain regions in SLE patients with and without NP involvement, and additionally, in white matter hyperintensities (WMHs), the most common MRI pathology in SLE patients. MATERIALS AND METHODS We included 3 T MRI images (conventional and DSC) from 64 female SLE patients and 19 healthy controls (HC). Three different NPSLE attribution models were used: the Systemic Lupus International Collaborating Clinics (SLICC) A model (13 patients), the SLICC B model (19 patients), and the American College of Rheumatology (ACR) case definitions for NPSLE (38 patients). Normalized cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) were calculated in 26 manually drawn regions of interest and compared between SLE patients and HC, and between NPSLE and non-NPSLE patients. Additionally, normalized CBF, CBV and MTT, as well as absolute values of the blood-brain barrier leakage parameter (K2) were investigated in WMHs compared to normal appearing white matter (NAWM) in the SLE patients. RESULTS After correction for multiple comparisons, the most prevalent finding was a bilateral significant decrease in MTT in SLE patients compared to HC in the hypothalamus, putamen, right posterior thalamus and right anterior insula. Significant decreases in SLE compared to HC were also found for CBF in the pons, and for CBV in the bilateral putamen and posterior thalamus. Significant increases were found for CBF in the posterior corpus callosum and for CBV in the anterior corpus callosum. Similar patterns were found for both NPSLE and non-NPSLE patients for all attributional models compared to HC. However, no significant perfusion differences were revealed between NPSLE and non-NPSLE patients regardless of attribution model. The WMHs in SLE patients showed a significant increase in all perfusion-based metrics (CBF, CBV, MTT and K2) compared to NAWM. CONCLUSION Our study revealed perfusion differences in several brain regions in SLE patients compared to HC, independently of NP involvement. Furthermore, increased K2 in WMHs compared to NAWM may indicate blood-brain barrier dysfunction in SLE patients. We conclude that our results show a robust cerebral perfusion, independent from the different NP attribution models, and provide insight into potential BBB dysfunction and altered vascular properties of WMHs in female SLE patients. Despite SLE being most prevalent in females, a generalization of our conclusions should be avoided, and future studies including all sexes are needed.

Abstract
We present an unusual case of a 37-year-old woman diagnosed with systemic lupus erythematosus presenting with right-sided weakness and altered mentation. On computed tomography and magnetic resonance imaging, marked intracranial calcifications were seen. These localized calcifications are speculated to be secondary to the necrotic focus of repeated episodes of vessel inflammation. However, the pathogenesis of cerebral calcifications is largely unknown.

Abstract
Objective This pilot study aimed to examine longitudinal changes in brain structure and function in patients with systemic lupus erythematosus (SLE) using diffusion tensor imaging (DTI) and neuropsychological testing. Methods Fifteen female SLE patients with no history of major neuropsychiatric (NP) manifestations had brain magnetic resonance imaging (MRI) with DTI at baseline and approximately 1.5 years later. At the same time points, a standardized battery of cognitive tests yielding a global cognitive impairment index (CII) was administered. At baseline, the SLE patients had mean age of 34.0 years (SD = 11.4), mean education of 14.9 years (SD = 2.1), and mean disease duration of 121.5 months (SD = 106.5). The MRI images were acquired with a 3T GE MRI scanner. A DTI sequence with 33 diffusion directions and b-value of 800 s/mm2 was used. Image acquisition time was about 10 minutes. Results No significant change in cognitive dysfunction (from the CII) was detected. Clinically evaluated MRI scans remained essentially unchanged, with 62% considered normal at both times, and the remainder showing white matter (WM) hyperintensities that remained stable or resolved. DTI showed decreased fractional anisotropy (FA) and increased mean diffusivity (MD) in bilateral cerebral WM and gray matter (GM) with no major change in NP status, medical symptoms, or medications over time. Lower FA was found in the following regions: left and right cerebral WM, and in GM areas including the parahippocampal gyrus, thalamus, precentral gyrus, postcentral gyrus, angular gyrus, parietal lobe, and cerebellum. Greater MD was found in the following regions: left and right cerebral WM, frontal cortex, left cerebral cortex, and the putamen. Conclusions This is the first longitudinal study of DTI and cognition in SLE, and results disclosed changes in both WM and GM without cognitive decline over an 18-month period. DTI abnormalities in our participants were not associated with emergent NP activity, medical decline, or medication changes, and the microstructural changes developed in the absence of macrostructural abnormalities on standard MRI. Microstructural changes may relate to ongoing inflammation, and the stability of cognitive function may be explained by medical treatment, the variability of NP progression in SLE, or the impact of cognitive reserve.

Abstract
INTRODUCTION Neurological manifestations although common in Systemic Lupus Erythematosus (SLE), are often not recognized due to their diversed and varied presentation. Therefore, the study was planned to highlight the pattern of neurological involvement in SLE to help in early recognition. AIM To study the pattern of neurological involvement in SLE and its correlation with disease activity and different investigation. MATERIALS AND METHODS This hospital based prospective observational study was carried out from August 2009 to July 2010. Diagnosed cases of SLE [based upon American Rheumatism Association (ARA) criteria] who presented with neurological manifestations at the time of diagnosis or develop during the course of the disease were included in the study. They were assessed clinically and investigated with neuroimaging and neurophysiological tests as applicable. RESULTS In total, 52 consecutive patients with SLE were evaluated, 92% were female. The most common age group was 21 to 25 years. Nervous system involvement was found in 19 (36.54%) patients. Cognitive impairment was the most frequent manifestation, present in 11 (57.89%) patients followed by seizure disorder in eight patients (42.1%). Peripheral neuropathy was diagnosed in eight (42.1%), acute confusional state in six (31.57%) and headache and depression was diagnosed in five (26.31%) patients each. Less common manifestations were psychosis, movement disorder and aseptic meningitis. Percentage of neurological manifestations directly correlated with disease activity. A significant difference was found in Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score between the patients with Neuro Psychiatric Systemic Lupus Erythematosus (NPSLE) and those without NPSLE (32.42±16.34 Vs 17.3±10.6). CONCLUSION Neurological involvement in SLE is seen relatively early in the course of the disease with cognitive impairment being the most common manifestation and correlate with disease activity.

Abstract
Neuropsychiatric (NP) manifestations are found in approximately 25% of children and adolescents with pediatric SLE (pSLE). In 70% of those, NP involvement will occur within the first year from the time of diagnosis. Headaches (66%), psychosis (36%), cognitive dysfunction (27%) and cerebrovascular disease (24%) are the most common presentations. The support of a psychiatrist is often required. Anti-phospholipid antibodies are associated with distinct NP disease entities and may be implicated in the pathogenesis of several manifestations of NP-pSLE including chorea, cerebrovascular disease and seizures. The role of novel auto-antibodies and imaging modalities is currently explored. The treatment of NP-pSLE is not based on prospective studies; however, an immunosuppressive combination therapy consisting of high doses of prednisone and a second line agent such as cyclophosphamide or azathioprine is commonly suggested for children with NP-pSLE. The role of novel therapies is currently studied. The outcome of children with NP-pSLE is relatively good. The overall survival is 95—97%, 20% of children experience a disease flare during childhood and 25% have evidence of permanent neuropsychiatric damage. Lupus (2007) 16, 564—571.

Abstract
Systemic lupus erythematosus (SLE) is a systemic autoimmune disease characterized by the presence of antinuclear antibodies and other autoantibodies, as well as a clinical course that is characterized by flares and remissions. The clinical presentation is diverse, ranging from a mild disease characterized by rash and arthritis to a severe life-threatening disease involving multiple organs. Approximately 25% of children with SLE have neuropsychiatric manifestations of SLE, which are a major cause of morbidity and mortality. Neuropsychiatric symptoms may be the initial presentation of SLE in children. The mortality rate is relatively low, but morbidity may be significant and permanent damage can occur. This article discusses the importance, known pathophysiologic mechanisms, clinical approach, and evidence-based therapeutic options for the diagnosis and management of neuropsychiatric lupus erythematosus in children and adolescents.

Abstract
Chorea is a movement disorder that may be found in children due to several causes. Here we focus especially on Systemic Lupus Erythematosus associated chorea. First we outline its epidemiology, hypothesized pathogenesis, clinical presentation and treatment, then we report four significant clinical cases, which represent well the extreme variability of set of symptoms that may accompany lupus chorea. Our experience, according to literature, suggests that choreic movements in a child should alert the pediatrician and lead him to investigate a potential neurological involvement of Systemic Lupus Erythematosus.

Abstract
Neuropsychiatric systemic lupus erythematosus (NPSLE) is the least understood, yet perhaps the most prevalent manifestation of lupus. The pathogenesis of NPSLE is multifactorial and involves various inflammatory cytokines, autoantibodies, and immune complexes resulting in vasculopathic, cytotoxic and autoantibody-mediated neuronal injury. The management of NPSLE is multimodal and has not been subjected to rigorous study. Different treatment regimens include nonsteroidal anti-inflammatory drugs, anticoagulation, and immunosuppressives such as cyclophosphamide, azathioprine, mycophenolate mofetil, and methotrexate. For refractory NPSLE, intravenous immunoglobulin (IVIG), plasmapheresis, and rituximab have been used. Adjunctive symptomatic treatment complements these therapies by targeting mood disorders, psychosis, cognitive impairment, seizures or headaches. Several new biological agents are being tested including Belimumab, a human monoclonal antibody that targets B lymphocyte stimulator. This review focuses on the pathophysiology, treatment, and new potential therapies for neuropsychiatric manifestations of systemic lupus erythematosus.

Abstract
Systemic lupus erythematosus (SLE) and multiple sclerosis (MS) are chronic immunologic diseases that can cause cognitive dysfunction. MS is a central nervous system (CNS) disease characterized by demyelination and progressive brain atrophy. SLE is an autoimmune disease capable of damaging multiple organ systems, including the CNS. Cognitive disturbances are seen in both SLE and MS. The present study is concerned with understanding the similarities and differences between the cognitive profiles of SLE and MS as well as the relationship between cognitive impairment and vocational disability in these patients. We examined 47 SLE patients, 47 MS patients, and 44 healthy controls. The groups were well matched on demographics and the patient groups were also matched on disease duration and severity. Group comparisons revealed that generative verbal fluency and visual-spatial memory are more profoundly affected in MS than SLE; whereas depression, fatigue, and working memory deficits are similarly involved in both diseases. Logistic regression analysis revealed that executive function, in particular, was predictive of vocational outcomes in SLE and MS patients.

Abstract
Chorea may occur in patients with SLE with a frequency estimated at 1 to 3% in adults and up to 9% in paediatric lupus. Chorea is frequently a presenting feature, and is strongly related to the presence of antiphospholipid antibodies. A treatment with antiplatelet agents and hydroxychloroquine is generally sufficient. During follow-up, the patients with chorea have a significant higher risk to develop thrombotic events (mainly arterial). They also have an excess risk of obstetric morbidity and valvular disease. The prescription of antiplatelet agents and adequate management, especially during pregnancy, can probably reduce this risk.

OBJECTIVE Working memory (WM) deficits have been reported previously in systemic lupus erythematosus (SLE), but the relationship between information processing speed (PS) and WM deficits in SLE is unknown. This study examined whether or not PS slowing could account for the WM deficits observed in SLE. METHOD A visual n-back task was used to measure simple and complex PS and WM in 40 SLE patients and 36 healthy controls. Simple PS was defined as reaction time (RT) to correct responses under a very low WM load condition (0-back), while complex PS was defined as RT to correct responses under moderate and high WM load conditions (1 and 2-back). RESULTS The results showed that SLE patients performed as well as the controls at the lower WM load conditions but had fewer correct responses than controls under the highest WM load condition (2-back). SLE patients had slower RTs than controls under all conditions, but they had relatively greater RT slowing than controls under the higher WM load conditions. Further, when RT for simple PS was subtracted from complex PS, SLE patients still showed slower complex PS for the 1- and 2-back compared with controls. Both simple and complex PS slowing were related to poorer accuracy scores on the 2-back condition, only for the SLE group. CONCLUSIONS The n-back task provides a sensitive measure of PS and WM. The results suggest that PS deficits alone could not account for the WM deficits in SLE. Disease duration, disease activity, and depression did not appear to account for the observed PS and WM deficits.

Abstract
Brain abnormalities have been documented by neuropsychological assessment as well as a variety of neuroimaging techniques in patients with systemic lupus erythematosus (SLE). Conventional neuroimaging in patients with neuropsychiatric disease (NPSLE) typically discloses periventricular white matter (WM) hyperintensities, infarcts, hemorrhages, and cerebral atrophy. In SLE patients with none of these findings, sophisticated neuroimaging techniques have recently supported associations between microstructural WM abnormalities and abnormal attention, executive function, and processing speed. This mild cognitive dysfunction in SLE (MCD-SLE), which may result from early myelinopathy, precedes the more severe cognitive dysfunction of NPSLE, related to more obvious WM and neuronal damage.

Abstract
A 13-year-old girl with a known diagnosis of systemic lupus erythematosus presented with seizures and psychosis. An electroencephalogram (EEG) revealed continuous, non-evolving periodic lateralized epileptiform discharges (PLEDs) in the left temporal region, which did not resolve with benzodiazepine. A magnetic resonance imaging (MRI) brain scan demonstrated a focal hyperintensity in the left medial temporal and left occipital lobes, left thalamus and bilateral cerebellar white matter, with evidence of vasculitis in the magnetic resonance angiography. Intravenous immunoglobulin was given because of failed steroid therapy, which resulted in a full resolution of clinical, EEG and MRI abnormalities. Lupus cerebritis should be considered as a possible aetiology in PLEDs, and immunoglobulin can be effective in neuropsychiatric lupus.

Abstract
Among the collagen vascular diseases neurologic manifestations have been most commonly recognized and well-studied in systemic lupus erythematosus (SLE, lupus). Neurologic manifestations are less prevalent in other systemic inflammatory and autoimmune disorders. This review focuses on the clinical presentation, pathophysiology, and treatment strategies of neuropsychiatric lupus (NPSLE) in children and adults.

Abstract
Classic immunologic teaching describes the brain as an immunologically privileged site. Studies of neuroimmunology have focused for many years almost exclusively on multiple sclerosis, a disease in which inflammatory cells actually infiltrate brain tissue, and the rodent model of this disease, experimental allergic encephalitis. Over the past decade, however, increasingly, brain-reactive antibodies have been demonstrated in the serum of patients with numerous neurological diseases. The contribution these antibodies make to neuronal dysfunction has, in general, not been determined. Here, we describe recent studies showing that serum antibodies to the N-methyl-D-aspartate receptor occur frequently in patients with systemic lupus erythematosus and can cause alterations in cognition and behavior following a breach in the blood-brain barrier.

Abstract
Imaging techniques play a pivotal role in securing the diagnosis of large vessel vasculitis, and in demonstrating internal organ involvement in connective tissue diseases. In large vessel vasculitis, angiography is useful in demonstrating vessel stenoses or aneurysms. However, angiography is unable to reveal initial lesions such as vessel wall oedema and thickening, and is thus not useful to make an early diagnosis. In contrast, colour Doppler ultrasonography, computerized tomography angiography, and magnetic resonance imaging/angiography are able to delineate both the vessel wall and the lumen. Therefore, they may show vessel wall alterations when the lumen is still unaffected on angiography. 18fluorodeoxyglucose positron emission tomography does not visualize the vessel wall, but is very sensitive in revealing inflamed vessels. All of these investigations have also been used to follow up patients over time and to monitor response to treatment. In connective tissue diseases, imaging techniques are particularly useful to study internal organs, especially the brain and lung. Magnetic resonance imaging is the investigation of choice to detect and monitor brain disease, while computerized tomography is the best procedure for lung disease. However, since most imaging findings are not entirely specific for any given condition, it is important to interpret the results of imaging in the broader clinical context.

Abstract
OBJECTIVE To analyze the clinical significance of hyperintense white matter (WM) lesions in both symptomatic and asymptomatic systemic lupus erythematosus (SLE) patients. METHODS We studied 120 consecutive SLE patients and 44 healthy volunteers. Fluid attenuated inversion recovery and T2-weighted magnetic resonance images (MRI) were used for visual and semiautomatic volumetric measurements. RESULTS At baseline, 61 MRI were normal and 59 had hyperintense WM lesions. Mean volumes of WM lesions were 96.14 (SD = 85.14) mm(3) in T2 weighted and 197.2 (161.13) mm(3) in FLAIR images. The volume of WM lesions was associated with age (r = 0.45; p = 0.01), total corticosteroid dose (r = 0.53; p = 0.001), and Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index scores (r = 0.55; p = 0.002). After a median follow-up time of 24 months (SD = 2.3; range = 12-28 months), 20 patients had still normal MRIs, 30 patients had stable MRI findings, and 30 had new WM lesions. Predictors for new or increased WM lesions were past central nervous system manifestations (p = 0.001; OR = 12.2; 95% CI = 3.5-21.2), antiphospholipid antibodies (p = 0.003; OR = 6.9; 95% CI = 2.1-15.3); Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index scores (p = 0.002; OR = 7.2; 95% CI = 1.4-17.8) and higher dose of total corticosteroid dose (p = 0.01; OR = 2.4; 95% CI = 1.4-6.7). CONCLUSION Small hyperintense WM lesions in SLE are associated with central nervous system symptoms and antiphospholipid antibodies, and progress over time in patients with more severe SLE. Therefore, in the context of SLE, these lesions are likely consequences of central nervous system damage and not mere incidental finding.

Abstract
BACKGROUND Headache in patients with systemic lupus eryhtematosus (SLE) is considered a common neurological finding, although the relationship is unclear. Another obscure point is the relationship between headache and neuroradiologic findings in these patients. AIM In this study, we aimed to evaluate the correlation between headache characteristics and intracranial lesions in SLE patients. METHODS AND RESULTS Forty-eight SLE patients were chosen from those referred to our clinic depending on the American Collage of Rheumatology (ACR) criteria at the same time or after the diagnosis of SLE. Headache classification was done regarding the ICD-II criteria in the patients. Headache severity was assessed by visual analog scale (VAS), and subjects with VAS > or = 4 were included in the study. Patients were divided into two groups according to magnetic resonance imaging (MRI) findings: abnormal MRI (lesion positive) and normal MRI (lesion negative). On MRI, intracranial lesions were detected in 37.5% (n = 18) of the patients, and no lesion was found in 62.5% (n = 30). Headache characteristics were as tension type in 54.1% (n = 26) and migraine like in 39.6% (n = 19) of all patients. Imaging findings were mostly as periventricular and subcortical focal lesions, ranging from 3-22 mm in diameter. A significant correlation was found between abnormal MRI findings with advanced age and prolonged disease duration (p = 0.018, p = 0.016). CONCLUSIONS As a conclusion, a detailed neurologic evaluation and radiologic investigation, if necessary, should be performed in SLE patients with prolonged disease and advanced age, regardless of headache characteristics.

Abstract
Neuropsychiatric (NP) events are severe manifestations of systemic lupus erythematosus (SLE) and relate to poor outcome. The aims of this study are to investigate the NP manifestations of SLE and to identify the predictive factors for clinical outcome. There was a retrospective review of 240 hospital patients with primary NP events of SLE (NPSLE) from 1990 to 2004. Neuropsychiatric manifestations, SLE disease activity index (SLEDAI) score, System lupus International Collaborating Clinic/American College of Rheumatology Damage Index (SLICC/ACR-DI) score, magnetic resonance imaging (MRI) findings, treatment and mortality rate were included for analysis. From this group of patients, 15 NP syndromes were identified. The most frequent manifestation was headache, followed by seizure. The mean SLEDAI and SLICC/ACR-DI scores were 19.9 +/- 6.9 and 3.5 +/- 1.6, respectively. Abnormal MRI features were found in 67% (61/91) patients. At least one intrathecal (IT) injection of methotrexate (MTX) plus dexamethasone (DXM) was administered to 109 (45.4%) patients. High dose (1 g) intravenous methylprednisolone pulse therapy (IVMP) was administered to 167 (69.5%) patients. Multifactor analysis revealed that high SLICC/ACR-DI scores and sets of concurrent NP symptoms were independently associated with poor outcome, whereas pulse IVMP and IT injection of MTX plus DXM were protective factors against poor outcome. From our data, NPSLE is heterogeneous and is usually associated with high disease activity and organ damage scores. High SLICC/ACR-DI score and having more than two sets of NP symptoms are the predictors for poor outcome, whereas pulse IVMP and IT injection of MTX plus DXM can improve the prognosis.

Abstract
A variety of neuropsychiatric findings may complicate systemic lupus erythematosus (SLE) and pose diagnostic and therapeutic dilemmas. We describe the clinical and radiographic features of posterior reversible encephalopathy syndrome (PRES) and distinguish PRES from other conditions seen in SLE. Patient charts and magnetic resonance imaging (MRI) findings of four patients with SLE on immunosuppressive therapy with acute or subacute neurologic changes initially suggesting cerebritis or stroke were reviewed. The English language literature was reviewed using the Medline databases from 1996-2006 for other reports of PRES with SLE. Literature review yielded 26 other SLE cases reported with PRES. SLE patients with PRES were more commonly on immunosuppressive drugs, had episodes of relative hypertension, and had renal involvement. Characteristic findings are seen on MRI, which differentiate PRES from other CNS complications of SLE. Clinical and radiographic resolution of abnormalities within 1-4 weeks is typically seen. PRES has been increasingly recognized. Reversible changes are found on brain MRI accompanied by sometimes dramatic signs and symptoms. The therapeutic implications for separating PRES from stroke or cerebritis are important. We propose that PRES should be considered in the differential diagnosis in SLE patients with new-onset neurologic signs and symptoms.
